Need help wiping my 9530

I have a couple questions. 1. I have .122/.153 which was put over .113 installed on my storm. Working great but think I wanna try V3.5. Is there that much difference in the OS? With that said, How do I go about using JL Cmder to wipe the phone, I've tried it before but JL Cmder never found connected with my phone. 2. Where can I dl JL Cmder? I deleted it from my computer and now I cannot find the link to get it. thanks for your guys help, much appreciated!
